"A total of 17 foundations committed £5m in 2010 to fund a series of rehabilitative interventions for three groups of 1,000 male offenders sentenced to less than 12 months at Peterborough prison. However, investors will get their money back in 2016 if there is an average fall in reconviction events of at least 7.5 per cent across the first and second groups. There were intended to be three groups, but the third group will no longer go ahead after the pilot was cancelled by the MoJ in April."
